Jesus says to anyone who uses their faith or lack of faith to excuse their acts of disobedience to his call: First obey, do the external works, let go of what binds you, give up what is separating you from God's will! Do not say, I do not have the faith for that. You will not have it so long as you remain disobedient, so long as you will not take that first step. Do not say, I have faith, so I do not have to take the first step. You do not have faith, because and so long as you will not take that first step. Instead, you have hardened yourself in disbelief under the appearance of humble faith.
~ Dietrich Bonhoeffer
